Asp.Net MVC2 Clientside Validation Task with Prefixed Controls

Question

The problem is this: when I put 2 controls of the same type on the page, I need to specify different prefixes for the binding. In this case, the validation rules created immediately after the form are incorrect. So, how to get the job of checking the client for the case ?:

page contains:

<%
    Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.PhonePhone, Prefix = "PhonePhone" });
    Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.FaxPhone, Prefix = "FaxPhone" });
%>

ViewUserControl <PhoneViewModel> control:

<%= Html.TextBox(Model.GetPrefixed("CountryCode"), Model.Phone.CountryCode) %>
<%= Html.ValidationMessage("Phone.CountryCode", new { id = Model.GetPrefixed("CountryCode"), name = Model.GetPrefixed("CountryCode") })%>

where it Model.GetPrefixed("CountryCode")simply returns "FaxPhone.CountryCode" or "PhonePhone.CountryCode" depending on the prefix

<% using (Html.BeginHtmlFieldPrefixScope(Model.Prefix)) { %>
   <%= Html.TextBoxFor(m => m.Address.PostCode) %>
   <%= Html.ValidationMessageFor(m => m.Address.PostCode) %>
<% } %>

public static class HtmlPrefixScopeExtensions
{
    public static IDisposable BeginHtmlFieldPrefixScope(this HtmlHelper html, string htmlFieldPrefix)
    {
        return new HtmlFieldPrefixScope(html.ViewData.TemplateInfo, htmlFieldPrefix);
    }

    private class HtmlFieldPrefixScope : IDisposable
    {
        private readonly TemplateInfo templateInfo;
        private readonly string previousHtmlFieldPrefix;

        public HtmlFieldPrefixScope(TemplateInfo templateInfo, string htmlFieldPrefix)
        {
            this.templateInfo = templateInfo;

            previousHtmlFieldPrefix = templateInfo.HtmlFieldPrefix;
            templateInfo.HtmlFieldPrefix = htmlFieldPrefix;
        }

        public void Dispose()
        {
            templateInfo.HtmlFieldPrefix = previousHtmlFieldPrefix;
        }
    }
}
